9. PRECAUTIONS ON TEST RUN
●
Request that the customer be present when the test run is performed.
At this time, explain the operation manual and have the customer perform the actual steps.
●
Check that the 220 – 240 VAC power is not connected to the inter-unit control wiring
connector terminal.
* If 220 – 240 VAC is accidentally applied, the indoor unit control PCB fuse will blow in order
to protect the PCB.
In this case, make the wiring correctly.
In case of Type 15, 22, 28, 36, disconnect the 2P connectors (OC) that are connected to
the indoor unit control PCB, and replace them with 2P connectors (EMG).
In case of Type 45, 56, 73, 106, reconnect the connector to pins 2 and 3 from pins 1 and 2
on the 3P DIP pin (EMG).
If the operation is not activated even if the short circuit pin is reconnected, cut the jumper
on the indoor unit control PCB.
(Be sure to turn the power OFF before performing this work.)
